external wastegate question
 

i have been lookin at my wastegate, and im a little confused on how to install it. well i have it on the manifold, but there is a hole on the top cap, and on the bottom of the wastegate. both are threaded so i dont know what to do with them. i have been told that the top one has to be vented, so i dont need to put a bolt in there. but its the bottom one im not sure about. should i leave that unblocked also? thanks

leave the top as is but you'll need a barbed fitting for the bottom one cause that runs to a vac source

Re: external wastegate question
 

so with the bottom one, would i just run it to any vaccum source, or is there one you recommend i run from. ive been told i can run a boost controller from it, is that actually posssible? i was asking quesions on how to up the boost levels on the external waste gatelast night. i was told to take the top hat off and put a spacer on top of the spring to raise the spring tension. i took it apart last night and its the most huge pain in the ass to put back together, let alone when i have it on the motor and in the car. so i think a boost controller would be a good idea if i have to go through that much trouble to change boost levels. any recommendations on boost controllers and what vaccum line to run the waste gate off of. thanks

With an electronic boost controller you'll also need to run the top fitting. As for vac source I've never had a problem running it off the brake booster.

Re: external wastegate question
 

I don't know about putting a spacer in? I wouldn't recomend that, best way to raise boost would be to put the correct spring in for the level of boost you want to run, a boost comtroller would be fine too but may not be as reliable, I run my wastgate of of the PCV vac line but any should work
